Safety risk assessment of heritage buildings in metro construction based on SPA theory: a case study in Zhengzhou, China

Abstract

While the urban rail transit systems have been developed rapidly, the nearby heritage buildings and historic sites are facing possible threats of unexpected damages. In particular, a rail project has a potential impact on numerous heritage buildings and sites in an old city. Thus, to better protect these heritage buildings and sites, it is crucial for decision-makers to be able to rapidly and accurately evaluate these threats. Based on Set Pair Analysis (SPA) theory, this study developed a risk assessment model to assess the safety of heritage buildings adjacent to metro construction. In this model, the risk levels of adjacent heritage buildings are ranked. Moreover, this study establishes an assessment index system comprising 16 individual indexes among four categories related to heritage building, metro, soil, and management. The index system determines the interval values for each evaluation factor. To improve the reliability of the index weight, a linear weighting method was adopted. In this study, both subjective weights calculated via the Analytic Hierarchy Process (AHP) and objective weights calculated by the Clustering Weight Method (CWM) are analyzed comprehensively. Moreover, a case study was conducted by applying the proposed assessment model into assessing the structural safety risk of a heritage building adjacent to the Zhengzhou Metro Line Three. It was found the results of the proposed model were consistent with the Matter-Element (ME) method. The proposed model can be used to provide decision-making support for controlling risk on similar projects.

Green Preparation of Lightweight, High-Strength Cellulose-Based Foam and Evaluation of Its Adsorption Properties

“…Not only is the original network structure of the wet foam maintained, but also the gelatin elastic aggregates tend to be connected through the forces of the polar group interactions such as hydrogen bonds and so on during the aging process. At the same time, the gelatin elastic aggregates are pulled into the overlapping distance that exists between the cellulose [52]. Therefore, it reduces the pore size of the foam.…”

The Impact of Urbanization on Cultural Heritage Buildings in Jordan: As-Salt as a Case Study

“…As the world experiences rapid urbanization, the preservation of cultural heritage buildings becomes increasingly critical (Fu et al, 2023). In the context of global urbanization and heritage conservation, characterized by rapid urban growth, has far-reaching insinuations for cultural heritage worldwide (Ashrafi et al, 2021;Wang et al, 2020;Rössler & Lin, 2018).…”

Multi-Expert Multi-criteria Decision-making Model to Support the Conservation of Paramount Elements in Industrial Facilities

“…The responses collected were processed using the Analytic Hierarchy Process (AHP) and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), which enabled determining the weights of the criteria and the ranking of elements. Both methods were selected because of their wide acceptance and use in the field of heritage science [25][26][27][28], including applications in which they are coupled with expert elicitation [29,30]. In this study, the AHP and TOPSIS methods were also complemented with cluster analysis and a Distance-Based Weighting (DBW) approach, whose combination served to synthetise the results obtained according to the similarity of thought exhibited by the experts.…”
